Look back: George Zimmerman trial

"Good morning. 'F*****g punks, these a**holes all get away.' "With a greeting and an attention-grabbing quote from defendant George Zimmerman, prosecutor John Guy began his opening statement in the trial surrounding the killing of teen Trayvon Martin.

Zimmerman, a neighborhood watch captain, was accused of fatally shooting the 17-year-old Martin on Feb. 26, 2012, in Sanford, Fla. Martin was black, and Zimmerman identifies himself as Hispanic.
